Now when a plain man comes to the consideration of this book one question naturally strikes him at once: How do I know who wrote this book, or when it was written? What evidence or guarantee have I for its authentic character? To these questions we shall apply ourselves in the present chapter.

The title of the book as given in our Bibles does not offer us much help. The title varies in different manuscripts and in different ancient authors. Some writers of the second century who touched upon apostolic times call it by the name our Bibles retain, The Acts of the Apostles; others call it The Acts of the Holy Apostles, or at times simply The Acts. This title of "Acts" was indeed a very common one, in the second and third centuries, for a vast variety of writings purporting to tell the story of apostolic lives, as an abundance of extant apocryphal documents amply proves. The Acts of Paul and Thecla, the Acts of St. Thomas, of St. Peter, and of St. John, were imitations, doubtless, of the well-known name by which our canonical book was then called. Imitation is universally acknowledged to be the sincerest form of flattery, and the imitation of the title and form of our book is an evidence of its superior claim and authority. One of the oldest of these apocryphal Acts is a document celebrated in Christian antiquity as the Acts of Paul and Thecla. We know all about its origin. It was forged about the year 180 or 200 by a presbyter of Asia Minor who was an enthusiastic admirer of the Apostle St. Paul. But when we take up the narrative and read it, with its absurd legends and its manifold touches and realistic scenes drawn from the persecutions of the second century, and well known to every student of the original records of those times, we can at a glance see what the canonical Acts of the Apostles would have been had the composition been postponed to the end of the second century. The Acts of Paul and Thecla are useful, then, as illustrating, by way of contrast in title and in substance, the genuine Acts of the New Testament which they imitated.[11]

But then, some one might say, how do we know that the genuine Acts of the Apostles existed prior to the Acts of Paul and Thecla and the time of Tertullian, who first mentions these apocryphal Acts, and tells us of their forged origin? The answer to that query is easy enough. Yet it will require a somewhat copious statement in order to exhibit its full force, its convincing power.

Tertullian is a writer who connects the age of apostolic men, as we may call the men who knew the Apostles—Ignatius, Polycarp, Clement of Rome, and such like—with the third century. Tertullian was born about the middle of the second century, and he lived till the third century was well advanced. He was one of those persons whose chronological position enables them to transmit historical facts and details from one critical point to another. Let me illustrate what I mean by a modern example. Every unprejudiced thinker will acknowledge that the Rev. John Wesley was a man who exercised an extraordinary religious influence. He not only originated a vast community of world-wide extent, which calls itself after his name, but he also imparted a tremendous impetus to spiritual life and work in the Church of England. After the departure of Mr. Wesley from this life his mantle fell upon a certain number of his leading followers, men like Adam Clarke, the commentator; Jabez Bunting, the organizer of modern Wesleyanism; Thomas Coke, Robert Newton, and Richard Watson, the author of the Institutes of Theology. Several of these men lived far into this century, and there are at the present day thousands still alive who recollect some of them, while there are many still alive who can recollect all of them. Now let us draw a parallel with all reverence, and yet with perfect fairness. John Wesley began his life at the beginning of the eighteenth century as our Lord began His human life at the beginning of the first century. John Wesley's immediate disciples perpetuated their lives till the middle of the present century. Our Lord's apostles and immediate followers perpetuated their lives in some cases till well into the second century. At the close of the nineteenth century there are hundreds, to say the least, who remember Adam Clarke and Thomas Coke, who in turn were personally acquainted with John Wesley. In the last quarter of the second century there must have been many still alive—apostolic men, I have called them—whose youthful memories could bear them back to the days when the Apostle St. John, and men like St. Mark, and St. Luke, and St. Ignatius, still testified what they had personally seen and heard and known. Why, the simple fact is this, that in the year 1950 there will be still living numerous persons who will be able to say that they have personally known many individuals who were the friends and acquaintances of John Wesley's immediate disciples. Four long lives of ninety years, the one overlapping the other, will easily cover three centuries of time.

Let us dwell a little more on this point, for it bears very directly on Tertullian's witness, not only to the canon of the New Testament, but also to the whole round of Christian doctrine. It is simply wonderful what vast tracts of time can be covered by human memory even at the present day, when that faculty has lost so much of its power for want of exercise, owing to the printing-press. I can give a striking instance from my own knowledge. There is at present an acquaintance of mine living in this city of Dublin where I write. He is hale and hearty, and able still to take the keenest interest in the affairs of religion and of politics. He is about ninety-five years of age, and he has told me within the last twelve months that he remembers quite well a grand-aunt of his born in the reign of Queen Anne, who used to tell him all the incidents connected with the earliest visits of John and Charles Wesley to Ireland about 1745. If Tertullian's experience was anything like my own, he may quite easily have known persons at Rome or elsewhere who had heard the tale of St. Paul's preaching, labour, and miracles from the very men whom the Apostle had converted at Antioch, Damascus, and Rome. I can give a more striking instance still, which any reader can verify for himself. Mr. S. C. Hall was a writer known far and wide for the last seventy years. About the middle of this century Mr. Hall was at the height of his popularity, though he only passed to the unseen world within the last year or so. In the year 1842 he, in union with his accomplished and well-known wife, composed a beautifully-illustrated work, published in three volumes, called Picturesque Ireland, which now finds an honoured place in many of our libraries. In the second volume of that work Mr. Hall mentions the following curious fact bearing on our argument. He states that he was then (in 1842) staying at the house of a gentleman, Sir T. Macnaghten, whose father had commanded at the siege of Derry in 1689, one hundred and fifty-three years before. Yet vast as the distance of time was, the explanation which he offered was easy enough. The Macnaghten Clan was summoned to assist in the celebrated siege of Derry. They refused to march unless headed by their chief, who was then a boy of seven. The child was placed on a horse and duly headed his clan, who would follow him alone. That child married when a very old man, and his eldest son attained to an equally patriarchal age, carrying with him the traditions of Jacobite times down to the reign of Queen Victoria. I could give many other similar instances, illustrating my contention that vivid and accurate traditions of the past can be transmitted over vast spaces of time, and that through persons who come into living contact with one another.[12]

Tertullian must have had ample means, then, of ascertaining the facts concerning the books of the New Testament from living witnesses. There is again another point we must bear in mind, and it is this: the distance of time with which Tertullian's investigations had to deal was not so vast as we sometimes imagine. It was by no means so great as the spaces we have just now referred to. We naturally think of Tertullian as living about the year 200, and then, remembering that our Saviour was born just two centuries before, we ask, What is the value of a man's testimony concerning events two centuries old? But we must bear in mind the exact point at issue. We are not enquiring at all about events two centuries old, but we are enquiring as to Tertullian's evidence with respect to the canonical Gospels and the Acts; and none of these was one hundred years old when Tertullian was born, about 150 A.D., while the Gospel of St. John may not have been more than sixty years old, or thereabouts, at the same date. Now if we take up the writings of Tertullian, which are very copious indeed, we shall find that the Acts of the Apostles are quoted at least one hundred times in them, long passages being in some cases transcribed, and the whole book treated by him as Scripture and true history. If we accept the ordinary view, that the Acts were written previously to St. Paul's death, the book was only a century old at Tertullian's birth. But we can come nearer to the apostolic times.

The Muratorian Fragment is a document which came to light by chance one hundred and fifty years ago. It illustrates the age of the Acts, and shows what wondrous testimonies to the New Testament scriptures we may yet gain. Its story is a very curious and interesting one for ourselves. St. Columbanus was an Irish missionary who, about the year 600 A.D., established a monastery at Bobbio, a retired spot in North Italy. He gathered a library there, and imparted a literary impulse to his followers which never left them.[13] Some Irish monk a hundred years later than Columbanus employed his time in copying into a book an ancient manuscript of the second century giving a list of the books of the New Testament then received at Rome. This second-century manuscript enumerated among these the four Gospels, the Acts of the Apostles, and thirteen Epistles of St. Paul. Concerning the Acts of the Apostles, the Roman writer of this document, who lived about A.D. 170, says: "The Acts of all the Apostles are written in one book. Luke explains to the most excellent Theophilus everything which happened in his presence, as the omission of Peter's martyrdom and of Paul's journey into Spain manifestly proves;" a passage which clearly shows that about the middle of the second century the Acts of the Apostles was well known at Rome, and its authorship ascribed to St. Luke.[14] But this is not all. We have another most interesting second-century document, which proves that at the very same period our canonical book was known and authoritatively quoted far away in the south of France. It is hard to exaggerate the evidential value of the Epistle of the Churches of Lyons and Vienne written about the year 177, and addressed to their brethren in Asia Minor. That letter quotes the books of the New Testament in the amplest manner, and without any formal references, just as a modern preacher or writer would quote them, showing how common and authoritative was their use. Leader-writers in the Times or the Saturday Review often garnish their articles with a scriptural quotation; the late Mr. John Bright, in his great popular orations, loved to point them with an apt citation from Holy Writ; but he never thought it necessary, nor do journalists ever think it necessary, to prefix a formal statement of the place whence their texts have been derived. They presume a wide knowledge and a formal recognition of the text of the Bible. So it was in this epistle written from Lyons and Vienne, and in it we find an exact quotation from the Acts of the Apostles—"According as Stephen the perfect martyr prayed, Lord, lay not this sin to their charge."

But this is not the whole of the argument which can be derived from the Epistle of the Lyonnese Christians, which is given to us at full length in the fifth book of the Church History of the celebrated historian Eusebius. Their incidental notice of the Acts involves a vast deal when duly considered. The Epistle from Lyons implies that the Acts were received as authoritative and genuine in the churches of towns like Ephesus, Philadelphia, Smyrna, Miletus, where the memories and traditions of the Apostles were still vivid and living. Then, too, the Bishop of Lyons had suffered in this persecution. His name was Pothinus. He was the first Bishop of the Church of Lyons, and he died when he was more than ninety years of age, and may have been a disciple of an apostle, or of one of the first generation of Christians. At any rate, his memory would easily carry him back to the days of Domitian and the times of the first century; and yet the Church over which this first-century Christian presided accepted the Acts of the Apostles. The testimony of Pothinus helps then to carry back the Acts of the Apostles to the year 100 at least. But we can go farther still, and closer to apostolic times.

The Gospel of St. Luke and the Acts of the Apostles are, we may say, universally admitted to be by the same writer. The reference of the Acts to the Gospel, the unity of style and tone of thought, all demonstrate them to be the production of one mind. Any circumstance therefore which proves the early existence of the Gospel equally proves the existence of the Acts of the Apostles. Now we have proof positive that the Gospel of St. Luke occupied an authoritative position and was counted an apostolic and sacred writing at Rome in the early years of the second century, say between 100 and 150, because when Marcion, whom we might call a primitive Antinomian, wished to compile a gospel suited to his own purposes, he took St. Luke's Gospel, cut out whatever displeased him, and published the remainder as the true version. The perversion and mutilation of St. Luke's work shows that it must already have held a high position in the Church at Rome, or else there would have been no object in mutilating it. Marcion's treatment of St. Luke proves the use and position the Gospel and the Acts must have occupied in days when the converts and companions of the Apostles were still alive.[15] That is as far as we can go back by external testimony. But then we must remember what these facts involve—that the Gospel and the Acts occupied authoritative positions in various parts of the world, and specially in Rome, Gaul, Africa, and Asia Minor, in the generation next after the Apostles. Then let us take up the Book of Acts itself, and what does this book, known at Rome and throughout the Christian world at that early period, tell us? It informs us that it was the work of the writer of the Gospel, and that the writer was a companion of the Apostle Paul throughout the portion of his career sketched in the latter part of the book. The Christian Church has never pinned its faith to the Lukian authorship of either the Gospel or the Acts. The question of the authorship of these books is an open one, like that of the Epistle to the Hebrews. The Acts has been attributed to Silas, to Timothy, to Titus; but I may say, without going into any further details on this question, that every attempt to ascribe the Acts to any one else save to the beloved physician has failed, and must fail, because he was the real author, well known to the living tradition of the Church of Rome in the early part of the second century, as that tradition is handed down to us in the language of the Muratorian Fragment.

If we were writing a critical treatise, we should of course have to enter upon the full discussion of many questions which might here be raised. The Acts of the Apostles in its latter chapters plainly claims to be the work of an eye-witness. In its opening words, placed at the head of this dissertation, it claims to be the work of the author of the Gospel. All the facts fall into a simple, natural order if we accept the traditional testimony of the Church that the Acts and the Gospel were both of them written before the martyrdom of St. Paul, and were indited by the hands of St. Paul's companion St. Luke. Any other solution is forced, unnatural, and involves inconsistencies on every side. We may turn aside from this brief outline of the critical question, to some more purely spiritual reflections, simply referring those who desire more information on the questions of date and authorship to such exhaustive works as those of Dr. Salmon's Introduction to the New Testament; Dr. Westcott on the New Testament Canon; Dr. Charteris on Canonicity, or Meyer's Introduction to the Acts.
